Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a support structure for a portable terminal and a portable terminal including the support structure.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a support structure of a portable terminal for preventing deformation and a portable terminal including the support structure.

In general, portable terminals such as smart phones and tablet PCs are important in their performance. However, in order to reflect intuitive design and user's requirement to carry easily, It is being produced lightly.

Thin and light portable mobile terminals have advantages of easy to carry while there is a risk of deformation due to external impact or pressure. Particularly, in a tablet PC having a relatively large size among portable terminals, if the supporting structure is weak, there is a risk that the display panel may be damaged due to deformation.

Therefore, in general, the portable terminal is inserted with a support structure made of a metal material therein to prevent the outer shape from being deformed due to impact and pressure.

1 is a cross-sectional view showing a support structure in which a support plate is inserted in a conventional tablet PC.

Referring to FIG. 1, a conventional tablet PC has a structure in which a support plate made of a metal material is inserted between an upper plate including a display panel and a lower plate of a case, and a printed circuit board (PCB) .

Such a structure is disadvantageous in that it is highly stable against external deformation due to the support plate of the metal material, but the thickness of the tablet is thicker and the weight is increased by the thickness of the support plate.

2 is a cross-sectional view illustrating a support structure of a tablet PC in which a conventional support plate function is implemented through a lower plate.

2, in the case of a specific tablet PC such as an iPad, a lower plate is formed of an aluminum case so that the tablet PC is not deformed without insertion of a separate support plate.

However, such a structure has a problem in that it is not only weak against impacts as compared with the structure in which the support plate is inserted by directly attaching the circuit board on the lower plate, but also requires to bend the lower plate of the aluminum material in conformity with the case shape.

Accordingly, in order to solve the above-mentioned problems, there is a desperate need to develop an internal support structure of a portable terminal that can be thinned and lightened while preventing external distortion by a strong structure.

An embodiment of the present invention is to provide a support structure for a portable terminal that can prevent external deformation by using a lattice-shaped support plate while being thin and light in thickness, and a portable terminal including the support structure.

According to an aspect of the present invention, a support structure of a portable terminal includes: a lower plate formed at a lower portion of the portable terminal; A support plate provided on the lower plate and formed in a grid-like support structure including a plurality of openings; At least one circuit board inserted into an opening of the support plate; And an upper plate installed on the upper portion of the support plate.

Also, the size of the opening may be changed according to at least one of the size, number, and layout of the circuit board.

The supporting structure may include an elastic body having a thin cross-section bent in a " C "shape and having a bent angle at an acute angle, and the opposing surface is coupled from the side surface of the supporting plate to fix the circuit board inserted into the opening And a clip-type fixing member.

Further, the fixing member may be configured such that protrusions are formed on the inner side of the facing surface, and the protrusions are engaged with the inner edge of the supporting plate when the fixing member is engaged with the supporting plate.

The circuit board may be installed such that the first circuit board faces upward and the second circuit board faces downward according to the design structure of the component.

The support structure may further include a coupling member for coupling the circuit board and the support plate, wherein the coupling member includes a through hole formed at the center of the frame intersecting in a lattice shape of the support plate, And the fixing plate may be configured to be wide enough to fix a plurality of neighboring circuit boards at the same time.

Further, in accordance with one aspect of the present invention, a portable terminal comprises a support structure according to any one of the preceding claims.

According to the embodiment of the present invention, since the circuit board is inserted into the empty space of the support plate formed in the lattice form instead of the structure in which the circuit board is laminated on the conventional lower plate, the stability against deformation is increased, .

In addition, since the weight of the empty space can be reduced by constructing the support plate in a lattice form, the weight of the portable terminal can be reduced.
